Due to popular demand, Sony is expanding its PSPgo Free Game Offer until January 31st 2010. The promotion allows you to download a free game when you buy a PSPgo. After purchasing a PSPgo, simply sign-in (or sign-up) to the PlayStation Network and download a promotional theme onto your PSPgo. You will receive a email from Sony within a few days allowing you to download one of three new titles.

The titles available on offer include MotorStorm: Artic Edge, Gran Turismo PSP or Assassin’s Creed: Bloodlines. The offer is also available to existing PSPgo owners, so if you haven’t already downloaded the promotional theme, what are you waiting for?
